This study is designed to identify the current condition of male students ostracized as the black ship (Wangtta in Korean) in middle schools and the effects of the Guardian Angle program on the decrease in Wangtta. 428 frist graders of two junior high schools were devided into two groups, a test group (n=195) and a control group (n=233). SPSS/PC+ program was used for analysis of the data, including frequency analysis, ANOVA and x(sup)2-test. The outcome of research can be summed up as the following 74.7% of the subjects thinks that there is Wangtta going on in there classes. Wangtta often comes to pass during the recesses (74.2%) and lunch times (51.6%). Those who are easily exposed to Wangtta are most likely to be both snobbish and pedantic. Those who lead Wangtta turn out to be good at fighting (56.4%) and dominant in the hegemony of the class depending on the way of ignoring or not playing with the victims(69.3%) In the case of bearing witness to Wangtta. 36.9% of the subjects try to overlook the case. Now let me take a look at the effect of the guardian angle program on the decrease in Wangtta. The program has a significant effect on the decrease (p<0.05) in the number and the phenomena of Wangtta perceived by students in both advance and post tests. The program makes a significant difference in the aspects of students’ behavior in relation to Wangtta in a desirable way (p<.01) Though the sociality index of the victims doesn’t show any significant difference statistically, it exerts a generally positive effect.

Objective: Middle school girls who belonged to the concerned group in their school assessment were treated by sandplay for relieving their emotional and behavioral difficulties. The purpose of this study was to explore the change of the internal world of the girls through sandplay. Methods: Analytical psychology and sandplay theories were used for this exploration, especially Turner's (2005) content themes in sandplay. The participants were four first-grade girls. Pre-test measures, a 12-session sandplay program, and post-test measures were administered. Results: For the first girl, the initial phase was 1-6 (time trip), the intermediate phase was 7-9 (seeking for an inner island), and the final phase was 10-12 (seeking for a real stone). For the second girl, the initial phase was 1-5 (my heart was like cold weather), the intermediate phase was 6-10 (fallen, sick, and risen), and the final phase was 11-12 (trophy given to me). For the third girl, the initial phase was 1-5 (seeking for oasis), the intermediate phase was 6-10 (difficult trip for climbing with camel), and the final phase was 11-12 (discovering oasis). For the fourth girl, the initial phase was 1-3 (an island drowning shortly ), the intermediate phase was 4-10 (my unknowable mind), and the final phase was 11-12 (a tree growing well). Conclusion: This study showed psychological phenomena in the sandplay of four girls such as opposites and the union of masculinity and femininity as they explored their own identity. Drawing tests and counselling objects indicated positive changes; thus, these findings support the effectiveness of sandplay therapy for transforming the psyche of middle school girls.

Official nursing education of Korea under Japanese rule began in order to make the communication possible among Japanese medical men and Korean patients. It could generate high standard nurses from the beginning. Nurses licensure began in 1914 and the graduates of official nursing schools could get nurses licensure without further test. Official nursing education became the standard of R.N. education. The curriculum emphasized on Japanese and ethics first, and in order to produce nurse, practice second. In 1920 the shortage of nurse became serious problem, so the Japanese colonial authorities set up 5 official nursing school in large scale. In 1922 they revised the relevant laws and regulations to make the nursing licensure pass all over Japanese ruling area. 8-year preliminary education and 2 year curriculum became standard of official nursing education after then. Other nursing schools should satisfy this standard to let their graduate get nurses licensure without further test. Curriculum was revised to satisfy the dual goal of 'good housewife' and 'good nurse'. Every official nursing school tried to raise educational standard Nursing science was specialized and more emphasis was put on the occupational education. From the late 1930s, Japanese desperately needed additional manpower to replenish the dwindling ranks of their military and labor forces. They tried to produce more nurses by increase nursing school. Students had to do wartime work instead of study. Younger students could enter nursing school, and general school could produce R.N. In conclusion, nursing education of Korea under Japanese rule was determined by the official nursing education. The Japanese colonial authorities lead the official nursing education. It made nursing education fixed early and produced high standard R.N. But it made nursing education withdraw in late Japanese rule period. Nursing education of Korea began quite weak in the need of nursing and Korea herself. The weakness became a subject of nursing education of Korea after Japanese rule to produce better R.N..

These studies were carried out to investigate the properties of H-Y antigen purified by immunoaffinity chromatography using monoclonal H-Y antibody. Immunoaffinity column was prepared by the coupling of monoclonal antibody to the Aminolink Coupling Gel. Murine testis supernatant was applied onto the column and eluted by O.lM glycine-HCl buffer and 31${\mu}g$ of H-Y Ag was eluted from one testis. Purified H-Y Ag strongly reacted with Con A and lentil from 6 different kinds of lectins tested, which may indicate that sugar moiety of H-Y Ag is composed of glucose, mannose and their derivatives. Con A-sepharose affinity column was used to purified H-Y Ag based on that H-Y Ag is glycoprotein. The fraction eluted by 0.2M Me-${\alpha}$-D-mannoside from the column loaded with murine testis supernatant was identified to be H-Y Ag by dot blot test. Molecular weight of the purified H-Y Ag was estimated by Sepharose G-75 gel filtration and SDS-PAGE, and showing that it was about 67,000 dalton. In fluorescence test, the ratio of XY embryos and XX embryos was 1:1.

Objective : In the present study we analyzed neuroprotective and antiapoptotic effect of the difumarate salt S-15176, as an anti-ischemic, an antioxidant and a stabilizer of mitochondrial membrane in secondary damage following spinal cord injury (SCI) in a rat model. Methods : Three groups were performed with 30 Wistar rats; control (1), trauma (2), and a trauma+S-15176 (10 mg/kg i.p., dimethyl sulfoxide) treatment (3). SCI was performed at the thoracic level using the weight-drop technique. Spinal cord tissues were collected following intracardiac perfusion in 3rd and 7th days of posttrauma. Hematoxylin and eosin staining for histopatology, terminal deoxynucleotidyl transferase dUTP nick end labeling assay for apoptotic cells and immunohistochemistry for proapoptotic cytochrome-c, Bax and caspase 9 were performed to all groups. Functional recovery test were applied to each group in 3rd and 7th days following SCI. Results : In trauma group, edematous regions, diffuse hemorrhage, necrosis, leukocyte infiltration and severe degeneration in motor neurons were observed prominently in gray matter. The number of apoptotic cells was significantly higher (p<0.05) than control group. In the S-15176-treated groups, apoptotic cell number in 3rd and 7th days (p<0.001), also cytochrome-c (p<0.001), Bax (p<0.001) and caspase 9 immunoreactive cells (p<0.001) were significantly decreased in number compared to trauma groups. Hemorrhage and edema in the focal areas were also noticed in gray matter of treatment groups. Results of the locomotor test were significantly increased in treatment group (p<0.05) when compared to trauma groups. Conclusion : We suggest that difumarate salt S-15176 prevents mitochondrial pathways of apoptosis and protects spinal cord from secondary injury and helps to preserve motor function following SCI in rats.

This study was designed to grasp the degree of job stress affecting dental technicians and the degree of the symptoms of their job stress. With this in mind, the researcher selected a total of 170 dental technicians living in Seoul and Incheon, conducting a research in a period ranging from August 1,2001, to August 20, 2001. The researcher made use of a structured questionnaire whose reliability and feasibility are proved. The questionnaire is composed of a total of 55 questions: thirteen questions related to the subjects' general characteristics; 28 questions connected to the measurement of job stress and fourteen questions linked with the measurement of job-stress symptoms. The researcher analyzed the findings with the aid of SPSS(Statistical Package for Social Sciences). The research came to draw the following conclusions on the basis of frequency, percentage, T-test, and F-test, multiple regression. I. The analysis into the job stress of the subjects indicates that there is a significant difference in difficult questions among their work places, working hours, academic background, job satisfaction and jobs(P<.05). The job stress stands at 3.48 on the average, and the area of conflict among too much work and job performance turns out to be highly perceived. 2. The analysis into the degree of the symptoms of the job stress of the subjects shows that there is a significant difference in work place, working hours, job satisfaction and the continual maintenance of job(P<.05). The symptoms of job stress accounts for 2.65 on the average. Physical symptoms turn out to be highly perceived; The response 'My arms and legs are killing me' proves to stand for 3.03. 3. The correlation between job stress and the symptoms of job stress turns out to be significant(r=0.519, P<0.001), and there is a significant correlation between the average points of each job-stress area and the average points of the symptoms of job stress. All in all, it is necessary that dental technicians themselves should make positive efforts to control and relieve stress and that more efficient programs should be implemented with a view to dealing with stress.

The protective effects of the aqueous MeOH extracts of stem and root Acanthopanax koreanum Nakai against oxidative stress were investigated. Anti-oxidant activity of the stem extract of A. koreanum was observed in the DPPH free radical scavenging $(IC_{50}=58.7\;{\mu}g/ml)$ and the SOD test $(IC_{50}=17.52\;{\mu}g/ml)$. According to data analysis of cell survival ratio of normal fibroblasts, the skin irritation by both extracts from A. koreanum was concerned. However, in the skin primary parch test, both extracts obtained Grade I, which means that there was no skin irritation. After induction of oxidative irritation, cell survival ratio of normal fibroblasts was also monitored and it turned out that stress-inducing group with both extracts had more increased cell survival ratio. The cell extension of the stress-inducing group treated with the stem extract was most dominant in morphological study. Based on these results, the stem extract of A. koreanum showed the protective effect against oxidative stress on normal fibroblast.

Recently, remarkable progress has been made in both technology and production of optical elements including aspheric lens. Especially, requirements for machining glass materials have been increasing in terms of limitation on using environment, flexibility of material selection and surface accuracy. In the past, precision optical glass lenses were produced through multiple processes such as grinding and polishing, but mass production of aspheric lenses requiring high accuracy and having complex profile was rather difficult. In such a background, the high-precision optical GMP process was developed with an eye to mass production of precision optical glass parts by molding press. This GMP process can produce with precision and good repeatability special form lenses such as camera, video camera, aspheric lens for laser pickup, $f-\theta$ lens for laser printer and prism, and me glass parts including diffraction grating and V-grooved base. GMP process consist a succession of heating, forming, and cooling stage. In this study, as a fundamental study to develop molds for GMP used in fabrication of glass lens, we conducted a glass lens forming simulation. In prior to, to determine flow characteristics and coefficient of friction, a compression test and a compression farming simulation for PBK40, which is a material of glass lens, were conducted. Finally, using flow stress functions and coefficient of friction, a glass lens forming simulation was conducted.
